Agenda
- Model driven approach in Dutch SDI
- Take the semantic concept out of the model (from stand alone
datamodels to stand alone concepts)
- Compare semantics – creating semantic posters
- Publish semantics in a registry - vocabulary
- Keep the process goingGeo-semantics

Cross-sector harmonisation

What we have noticed
Data exchange is shifting from individualregistries to an
infrastructure of registries(2.0)
Focus on datasets is shifting to individualobjects of
interest.
Dutch INSPIRE data are relevant in Dutch Use cases

15 domains 34 domains 15 application domains (?)

INSPIRE Observation & Measurements
All relevant in the Dutch context
What about harmonisation? Is thismanagable?
Over 800 feature types
-
Handling SEMANTICS by OVERVIEW
What does a model editor need?
Use-case analysis and overview of used and existing
vocabulary.
Define and re-use of vocabulary: harmonising andre-using.

Handle on SEMANTICS by GOVERNANCE
Organising a process around harmonisation.

A harmonisation activity
Visualise semantics in posters: 3 steps:
1) Get all models into one environment
2) Re-classify all concepts
3) Create posters containing similar concepts.

Geo-semantics
An example: concepts related to administrative units and
addressing
Issues can be detectedand discussed
-
Publishing harmonisation issues
Geo-semantics
And commitment to resolve
ISO
New versions address issues
-
Next steps
Publishing semantics as linked data vocabulary: integrated
catalogue
Implement a uri strategy for publishing semantic concepts
Happy with INSPIRE registry
Re-using INSPIRE registry software to publish semantics in
RDF

Re-using INSPIRE Re3gistry software

Conclusions: Harmony in Semantics
Semantic harmonisation is a participative process
Organising the process is key
First you need to know where the issues are
Bring the overall semantic harmonisation process into the
version cycle of domainmodels
Semantic registries based on RDF will improve understanding and
re-use of concepts
